Well sell a load through the auction where i work (Daimler Chrysler fleet management) and they seem ok, most of the niggly problems are electrical ones with the gearbox, (especially if some fuckwit connects the battery booster pack the wrong way - it spikes the gearbox ecu and they wont run or even start after that...), gearlever position sensors are prone for failing, other than that they seem ok.

Mind you, if you crash you die...
