good deal
 

2002 f150 lariat w/ 113k 5.4 drove and sounded superb. Excellent condition in and out. 20" nice rims. Everything but the sunroof works perfect.

$7500. Good buy?

I think if you could get it for $65-7000 you'd be in better shape, but I'm a lowballer :)

If you bought it, you could sell the rims and tires for $500-$1000 and put some real ones back on the truck

If you are serious, I would go to a Ford dealer and ask them for a quote on diagnosing and fixing the sunroof. They'll give you an insane estimate that you can then take to the owner and use it to dicker the price down. Then you can probably fix it yourself for a fraction of the price if you even do

The only way I would suggest fixing a sunroof is by replacing it completely. In my experience, once they start having problems, they never stop.
