I have been pretty amazed at cold starts in that jetta. There have been a lot of mornings I go out thinking "no way is it gonna start, gonna have to dig out another vehicle", hop in hit the key and hear wraaar wraar super slow and then it fires up. It certainly doesn't like it at all, but it starts. I have often thought I should install the frostheater dealie for winter time, but it has never let me down on cold starts without it.
I generally do not like sedans, but I really like that little jetta. Stick, so it is sporty and fun to drive. Autos are dogs that can't get out of their own way. And only filling the 13 gallon tank once a month is pretty sweet too.
The PSD gets plugged in if temps drop below 30, just cause it runs like crap for too long when it starts cold. I put one of those boater plugs on the front bumper to make things easy.
