Working so close to GM, I'm frequently surrounded by managers driving their XTSs with manufacturer plates, towering over my car who's roof comes up to the XTS' beltline. I can't help but to think that although GM has arrived upon a favorable form language, they may have forgotten to take a step back to think why their cars aren't as popular as BMW or Mercedes. The proportion of the XTS is deplorable. If one squints their eyes, the XTS can be confused for a plump Jetta. So I had to shoop it; no change in wheel size or wheelbase, just a sunken DLO and sectioned body, with slight reductions in headlamp and grill height. I think the results speak for themselves. Too bad it takes more than 30 minutes to do this to a real car.
Thoughts regarding attention to proportion in modern vehicles?
