Nothing.
The SER is quite a machine. This is the fastest car I have ever owned. It is no corvette, but on the other hand it is less than a third of the price and is only three seconds slower (0-60 in 7.2 sec). It is the best bang for the buck for under $20000 hands down. There is no better feeling than pulling up to a stop light with the windows down and the sunroof open with the 300 watt stereo blasting (Which comes with a 10" sub) The car still has VTC (I didn't mistake that for VTEC) at 4000rpm except that it has a good power band at every range unlike the honda Vtec motors. You don't realize how fast the SER until you rev it to 5000 in 1st and 2nd, by the time you shift to third your going 55 and the cars behind you are a football field length away.
You have to get used the torque steer (which only happens past 4000 rpms when all the torque is available because it is front wheel drive) but you adjust quickly (just grip the steering wheel firmly) you won't run off the road, but it might swerve a bit, also the stock suspension is a lot firmer compared to a family sedan so you have to be careful driving because it is easy for the steering wheel to sometimes jerk after hitting a bump. NO COMPLAINTS WHAT SO EVER. This car is a BLAST to drive. The 6 speed makes it all the better, i have had my car for a month and I still look forward to driving it everyday.
Another thing is that few people own a SER. Get a car that stands out (they are offered in yellow, red or orange (which I have) if you want) from the rest unlike a civic.
P.S get the nismo intake, it is well worth the money. You can really hear the engine growl afterward, I freakin love it.
This one is for the person with no complaints because he's had his vehicle for ONLY one month. I give him seven months before he joins everyone else with all types of problems. GOOD LUCK BUDDY!
I've had mine for over two years now, one complaint, fuel pump had to be replaced. Hey, it was in warranty and they were servicing it anyway, so it wasn't a problem.
I still look forward to driving it, handles like a dream, I get many comments, and peeps in Hondas with the big ole stove pipe mufflers really look perplexed in my rear view mirror.
In the mean time, I drive it as hard as I like and I'm still getting 27-29 mpg.
I have a friend who has a 2002 model, he's had absolutely no problems out of his, but that model has a bad looking shifter.
