I am looking into getting either to use as a DD and possibly mod for fun. A few years ago I bought a modded Regal GS that was the fastest car I driven but it had small issues that I didn't take the time to sort out and I sold it (regrettably). I always wanted another (doesn't matter the body) and now the prices of the GXP are within my range so I thought of those too. Stock I assume the GXP is faster but with mods I thought the 3800 SC wins. Back when I had the Regal there were plenty of parts online for them but just checking ZZP and Intense websites looks like they provide less parts to mod so was wondering if I should just get the GXP and do intake, exhaust and tune or get another 3800 and do extensive mods. I would like a mid 13 sec car at the least.
What are your ideas?
