I usually build "American" stuff, and they all have engines, but since I have been a member here, I do look forward to working on my Aoshima's, Fujimi's and Tamiya "curbside" stuff to learn better weathering techniques, interior detailing, etc. Since I won't be concentrating on the engine and driveline details.
I do like the cost of Imports being considerably lower than most of my Revell's AMT/Ertl, MPC stuff, so for me price and the look of the car are huge factors for purchase. Plus if I decide to do something wild kit bash style, I really have to step up my crafting game.
