2006 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)
2 1/2 half years experience, 31500 miles. Replaced the battery this week, no other issues. Changed Bridgestones for Goodyear Eagle F1 A/S - 10,000 miles on the Goodyears, just do it. Upgrades - K&N Series 63 intake system, Magnaflow muffers (yeah they sound mean), upgraded floor mats and piano black dash trim kit. Adding LED taillights soon. White exterior/sand ultra lux leather interior. No Nav or optional paint. A+ build quality. Have some fun? Disconnect the battery overnight - drive the GXP hard the next day over several drive cycles. Becomes a REAL hot rod (I promise). Rare model - turns heads. Almost 20 mpg town w/27 highway. Wanna race?
Rarity/great looks - FAST - did I say FAST? Superior fuel economy - use premium only. Heads up display, paddle shifter. Details to a very high standard - red brake calipers with those plated wheels - A+. Flip down the seats? Becomes a pickup truck (not really but you get the picture).
K&N Series 63 intake system. Magnaflow mufflers, dash kit, floor mats/truck mat. LED tail lights. Use Meguiars products only for exterior maintenance. Treat yourself to the mufflers - then use the remote start and listen to your GXP "talk" to you as you walk up. Make your friends jealous.
