First off, clean out your flame trap and get a tune-up and all new filters. That might prevent your stalling issue. (or, learn how to drive stick) If the 240 is of a certain vintage, it might have the environmentally friendly (read: photo-degradable) wiring harness insulation, in which case you might start having electrical gremlins. see
www.brickboard.com for help.
Secondly, the 240 is a beefy monster with honking big bumpers made of metal. Unless you really got popped, I doubt you'll have any residual problems. The bumper shocks can get rusty depending on where the car has spent its life, and the mounts for them can come apart from the frame. You can crawl underneath and take a look just as good as a dealer, and for only 1/2 the cost! (pay yourself in new IPD anti-sway bars)
Thirdly, keep your 240 away from the dealership. Find an independent volvo specific shop- IPD is in your general vicinity and should be able to provide a recommendation.
keep that brick on the road!
