Congratulations. I had a 525i before

Congratulations. On Window tint, suggest you use a high quality shop or dealership. I had a 2001 525i before. The tint on my car was done by the dealer since I bought the car that was on the lot. Never had issues with the tint. If the tint quality is low, it may start to have wrinkles after some years. I like the 5 series. Very sporty and great control. Nice family car. More fun to drive at high speed than low speed. 528's accleration is sufficient if you are not the type that tries to race everyone on the road.
