GP'* feel cheap. If you ride in a GP with over 100k on it, it creaks and rattles and sounds like it is falling apart. Believe me, we have 4 of them. They aren't well built at all compared to an H-body. The '93 Olds 88 we have and the '00 SSEi feel like new cars when you drive them down the road, even though both have over 125k on them. A Grand Prix is a nice car, no doubt, it just doesn't have nearly the build quality of an h-body. I'm a Grand Prix nut, but I'd take the LSS over a GTP anyday. When my mom had her SSEi in the dealer to get the bubbling hood fixed, they gave her a '01 GP GT with 15k on it that was a lease turn in they had just gotten back. The interior was worn out, it creaked and rattled, the steering was loose, it felt like an old worn out car. I would've bet a lot of money it had 150k on it instead of 15. I was so sure I even put the autotap on it to see if the mileage in the PCM matched the mileage on the dash, and sure as **** it did. I've never seen an H-body with 15k on it that was anywhere near that worn out, EVER.
