I am a new member of this group and I'm seeking advice on purchasing a 2008 IS-250 which is in good condition with 48,642 Miles. However, it has been parked in a garage and not driven for 27 months. I recently replaced the battery and the engine started after 2 tries and idled smoothly thereafter. Any advice on what I should look for or check on the vehicle would be appreciated. How risky would my investment in this car be?
