My dad worked for Bud Moore as a Nascar mechanic in the early to mid '60s so I grew up with the roar of a 427. Dad did all his own work and I followed in his footsteps.
BMW's and Fords aren't all that much different, the BMW might have a few funny heads on some bolts but it is all just nuts and bolts.
I'm very blessed to live out in the county with plenty of space for a shop and no zoning requirements. I built a 30' x 40' shop with two rollup doors, a 30' workbench along the back wall and I have a two stage air compressor, four double-decker rollaround toolboxes and most recently, a quickjack. Love that thing.
