Original owner 2016, MP-215, resonator delete, sound symposer delete only mods when it was new. Still DD and road trip car, 70K miles and pulls like a train in 3rd. BTW, @ 9 years and no sunroof leaks, LOL! We use it often and glad we have it, I've had 3 sunroofs and never a leak in any. The secret is to use them so the seals do not take a permanent set.
