As you are all aware everywhere is cold and unpleasant laste few weeks, now having said all that I am a Grand Prix fan from way back and now own two of them. One of them is a 2008 GXP with 48 Km. but it is parked until summer and I am pondering doing some upgrades on it and when time permits I wanted to ask a few questions on that one, trying to avoid warranty issues. The second car is a 2004 Grand Prix GT and it has been a super set of wheels, and lives up to the legendary performance that I have come to expect, cold starting and day to day driving etc., my 04 has 137,000 Km, its my drive everywhere car. The first question I have of many to come is for my new 08 can I put a trickle charger on it and not have to remove the battery cables from the battery posts, any thoughts?. When I get a chance I will post a picture of both cars.
