I just purchased a 2000 Pontiac Bonneville SSEi with 61k miles.

I have no intention to increase performance. I just sold my Mitsubishi 3000GT and am looking for something dependable.

However are there certain performance modifactions that will improve mileage, engine and drivetrain life that are worth getting. I don't want to do anything to strain the engine but any aftermarket items that will increase performace are always great things to add.

Thanks in advance.
No pics of the car yet, but here is a pic of my old car.

Welcome.

Is that a VR4?

Nope it was an SL. 1993 with 155k miles when i sold her. Got 4k out of her. She had FIPK, 2.5 In Exhaust with downpipe and testpipe, lightweight pulley and removed resonator bottle. She was kinda slow cause it was heavy!(weigh in at over 3500 lbs!!!) But handles like a dream and just was a blast to drive. But could not keep a tranny. ATX tranny puked out on me 3 times. $2800 for a rebuilt tranny is insane too, couldn't dump anymore money into her even though the trannies were all under warranty. It was the time it took them to replace it that hurt the most. Atleast a week to receive tranny and installation and that was when they would send the right parts. Took two months one time!

I hope to have better luck with this car.

You will have better luck with this car. Bonnevilles are great cars, reliable too. But that 3000GT does look pretty good. What kind of rims are those?

They don't make them anymore they are out of Japan. They are Kozei Snipers 18x9. Have 265/35/18 Kumho Ecsta Supra tires on em. Still have them. Unfortunately don't think they will fit on this car.

Welcome!
