Hello i have a 2001 volvo s40 1.9t 98k miles. I love the car, unfortuntatly its been sitting in my garage for 3 years, cause i couldn't afford insurance. Now thats i have insured again, i was wondering if should hook it up, or is the mileage too high? Also any tips on what i should do,such as a tune up, since i havent done one since 67k miles, someone recommened a " maintance check", which includes flushing out my my transmission and engine, i never heard of this service but its it worth it, any recommandation on what to do??

P.S. the only upgrade i have is a eurotunning air-intake.
