Have to make my point again - that $3000 should be NO, it's waaaaaaaaaaay too much; betcha the dealer makes $1500-2000+ on it. Add $35 a year to your car insurance for roadside assist. Get a cell phone. Be absolutely sure that something you want to do to your car won't void any warranty you buy. If there's the slightest indication that you are 'racing' your car, i.e., modified air intake or maybe even custom wheels, you can kiss warranty coverage goodby w/the wrong company. You can buy the add-on, third-party extended coverage after you buy the car. Decision is easy: no to their extended warranty. Are they giving you any warranty - 30 days? Take a grand of your 'extra' money and put in a new savings account for unexpected car repairs and leave it there. Set aside another $500 for misc car stuff - we can talk about it.
To Do: (do not trust that they did all this - get salesperson and/or service mgr. to verify this. Ask for specific, detailed list of what was done to car.)
check engine oil level
Did they change the oil when they got the car? If so, exactly what oil do they use? What brand filter?
check coolant level when cold
check all fluid levels
check tire press, spare/jack/wrench/wheel lug lock key
do Carfax report (actually have them do it for you)
look for any kind of fluid leak
did they shampoo interior/trunk?
does the boot for the top come w/the car? (cost you up to $200 to find one)
did they buff/wax car? (ask them, lot of dealers use a detail service if not doing in-house)
what brand/model tire is on car & are all four the same?
is intake manifold all plastic?
Any sign the shocks/struts/serpentine belt/rad hoses have ever been replaced?
approximate life left on brake pads / tires?
know anything about repair history? any papers in car or owners manual to show where it may have been serviced before or who owned it?
then, when you get the car, PM me back, I have another list of stuff for you to do.
