They also came on a few of the "breadbox" Mini Van's.
Yes, they do sort of improve the looks, but not on a P-Type car... Esp since those wheels are only 6" wide, while the stock 14" P-Type wheels are 7" wide. With the 15's, your wheel flares will stick out, due to the 20mm offset.

The company is in Holland, MI.
The wheels definitely are flatter in profile than the 14x7 on the P type. I would imagine that a 1/2" spacer would space the wheel out better, but then you've got the issues of longer wheel studs and hub-centric centering of the wheel.
They list for US$155 per wheel less centre caps.
Worth a look for those who like the OEM look but want slightly larger diameter tires.
