I believe there used to be a difference, similar to GMC vs Chevrolet. But like those brands depending on the years, the products seem to get more similar, then migrate to differentiators, such as more bright-work (chrome) and differing body skin/grilles, etc.
The main difference these days between Sunseeker and Forester is body paint/decals, and the name. There may be differences in price, based mostly on dealer perception of the two nameplates, but you can purchase either nameplate and you'll get nearly the same product.
We purchased our Sunseeker because it was offered for a terrific sale price, and because it's what we had been looking at anyway. Had it been a Forester, we'd be Forester owners today!
