The electrical system shorted out and cut out the tail lights. That took two months to fix. Gas mileage is horrible; I've been getting an average of 14 miles a gallon (for you non-US measurers, that sucks) across all types of gasoline. Lately there's been a bunch of accelerator lag too.
It was cool in the beginning, but it just started to suck all of a sudden. I'd avoid this car like the plague.
You might want to buy the manual for it. I had the same problem with the lag in acceleration. New spark plugs, wires, fuel filter, and a bottle of fuel injector cleaner gave me back all the power and mileage (about 22 highway and 18 city). I have over 200k on my car now and have had it since 20k. Only major repairs have been suspension (old set worn) and water pump.
If you want to boost car performance change: air intake to performance cylindrical type filter, have your CPU sent to a performance shop. For about $250 dollars the will return it w/30 more hp and 20% better mileage.
