We got the wife a 1.8T beetle last year, & she absolutely loves it. Trying to talk her into a TDI beetle, but that may take some time lol.
I have 4 dodge cummins trucks, & run used filtered motor oil & biodiesel in 3 of them; I will prob run some bio in the jetta as well from time to time (the nearest station that sells it is 45 min away)
Plans are to get a trailer hitch for the jetta, & get one of those 3x6 cargo platforms that is a hitch mount behind the bumper like they sell at harbor freight (for running parts off craigslist for my trucks & cars). I will keep the body mods modest; this will be more of a utility car / parts runner for me, so no boat tails or anything like that
I have been reading a lot on deezlers posts; I will be looking into a downpipe upgrade too
