I can't comment on the engine specs, etc., but I will agree on the garage
space comment.
I was FORCED to have mine small.....very small.  Ran out of $$ when we
moved.
I had wanted a 30'X40' barnstyle...2 storey.  What I got was no separate
garage at all.
I ended up making it one end of the basement, as we put our minihome on a
basement, thus
my garage is only about 15.5'x17.5'........SMALL !

On one side of the garage is my Austin Mini Cooper I'm restoring and on the
other side I work on my other various
cars, like my 86 Golf Diesel.

Sure isn't a lot of EXTRA room, like for standing, sitting, tools, etc. 

LOL!
