Anyone who has some joker add a remote starter to an expensive, modern car is nuts.

I have a friend who had one put in his S70 and it sounded like a diesel after the installers repaired it twice because it would not start. I have NO CLUE what they could have done to the relatively nice car to cause it to sound like that!

When I buy a used brick, I have my dealer run it through their certified car check. It is way too expensive to repair a Volvo that has problems.

I get a nice two page report - I think that they can tell if an ant farted in the trunk.

I pay 1 hour's labor - add an hour if you want a compression check. Probably a good idea in your case.

I f the car looks good during the test, I usually tell them to put new plugs in and save the old ones. I use them as spares, besides I like to look at them.

An interesting story -

I was buying a used car off this dealer and before our final negotiations, I paid for a certified check.

The next day the salesman called me and offered to pay for half the cost because the service department would not let him look at the results!
