Aftermarket parts are an awesome idea to make your Smart car more unique than any other. Although some aftermarket parts will void your current warranty, the aftermarket part should come with a warranty for itself. IF anybody needs any recommendations for anything about their smart car, please feel free to ask. I researched into the smart car for 6 years before mine finally arrived and was one of the first people to put my name down for the reserve once it came up. I am currently working on a new audio system for the current premium sound package and working on a new exhaust that will increase all around performance. If you want to ask questions on where to buy rims, radios, floor mats, or anything, again, please feel free to write to me and I will give you my advice and where and how much for the cheapest price. Or, you can just write to me just to stop in and say hi because I won't smart car will!

Hi Brett, Your car looks great. I've had a blue/silver coupe since February. I don't plan to do too much to it. I've replaced the factory radio with an Alpine with ipod control and bluetooth, speakers, cocomats, and body-colored gas door. I'm thinking about the Breathless "touring" exhaust. Enjoy your car, thanks for the invite! Steve

go to and search for the armrest there. I'm waiting to spend the $278 to order one since I just upgraded the sound system in mine to a touch-screen navigation system. I did all the wiring and install myself if anyone has questions about that. I spend right at $1200 on the total system and since I did it myself I saved a ton on labor. I now have a Pioneer AVIC-D3 head unit (nav/cd/dvd/sirius/xm/bluetooth phone/bluetooth audio), Alpine 6 1/2" components in the door and I cut a hole just where the door starts to curve right behind where the dash comes to the door for the 1" tweeters (the factory tweets can't handle the power and I couldn't figure out how to get to them without ripping the entire dash out, Pioneer surface mounts for rear speakers and mounted them right above where the luggage cover pulls closed, an Infiniti bass link 10" sub behind the drivers seat in the luggage area. I'm very very happy with the sound but smartieparts is supposed to be designing a subwoofer and amp combo that will replace the styrofoam over the battery and house an 8" sub that fires under the dash. I'm hoping to change to that and save my luggage room when its available. If anyone needs to know about the wiring let me know. smart is no help with this since they haven't even given the dealers the wiring diagrams yet.

An arm rest would be nice.

Thanks for the advice on the audio system. I think I found a great installer locally, who also is a Smart owner, and has installed a kickin' system in his own Passion.

Hi Brett,

Here is another after market product for you to list, should you wish.

My wife and I are avid RV'ers so when we saw the Smart (I hate those lower case names!) we immediately decided that it was the ideal vehicle to be the 'dinghy' for our rig. We did not want to drag it, however, as that seems to me to be the ideal way to wear our bearings, seals, etc. And if a bearing started to squeal, there would be no one to hear that early warning. This scenario could get expensive, fast. And, even though MB says it can be dragged, I'll bet the warranty would not cover it under some very small print. Dunno about that, however, but I never met an car company that liked things made by outsiders. Whaddya think?

Another factor against this option is that you simply cannot back up a towed vehicle that has 4 wheels. on the ground Just won't work. And this applies to tow-dollies as well.

In any case, we decided we needed a trailer, which would preserve the condition of our smartie while traveling. Being an engineer, I designed what we wanted, took it to a local trailer manufacturer, made some mods, and off we went!

The next step was to offer it to other smart RV'ers, which we do through our company, Smart Sales, LLC, at our site,

I think you have a great topic going here and all sorts of ideas will come out of it, I'm sure.

Good luck!

I only paid about $49 for the smart car all weather floor mats which I currently use. Their is also a carpet version of this floor mat for about the same. You could also use universal floormats you can pick up at any auto parts dealership. My friend did that to his smart and it looks pretty good, but for the best fit, use the ones smart recommends. I can't see them being the amount that you told me they were, but I only paid $49. Also, smann makes a pair for about $85 that is custom made just for the smart. You can find it at

I'm interested in finding floor mats for my car however I'm not interested in spending $125.00 for the ones at the dealer which IMO are not that grate. I did find some custom cut ones on EBay for half the price but I was wondering what you have uncovered before I make my decision.

the current audio system is pretty bad. If you want, I can recommend a sub woofer upgrade held on by straps that I am going to do to my car when I start to work. Since it will be held on by straps, you can remove the sub woofer when you need to haul heavy loads or take a look at the engine and will not interfere with the look of the back. Also, the current speakers in the doors are only 4". The maximum you can put in the doors are 6.5" which I cam recommend from pioneer. Pioneer is unrivaled in sound. A great amp to power everything is the Memphis D class small amp that will power everything and fit right under the driver's seat. I can send you all the link you will need to research this audio system upgrade if you want all of it, but shop around on ebay and pioneer's website and the Memphis website. If you know any good radio shops that install and know what they do (not best buy or circuit city), then they should hook it all up for you. I am going to get the upgrade sometime in the middle of July and post pictures about it. Also, the pioneer double-din radio is extraordinary, but if you want a navigation system, you can buy that too. You will also need to buy a holder for the new audio system and be able to drill out more from the current ipod hookup in the glove compartment. Trust me, all this hard work will pay off because it desperately needs it. Any more questions; don't be afraid to write.

Hi Brett,

My wife & I are 1-day old owners of a Passion. We're really excited by the car, and are looking to upgrade a number of things. Any insight you can share on upgrading the speakers (or the amp/head unit if necessary) as well as wheel options would be great.
Thanks for sharing your time and help!
