I owned and drove a naturally aspirated (i.e. non-turbo) Troopy for about 4 years in Colorado. Around town, you'll never miss the power, and two lane back roads (flat or gentle hills) are mostly fine, but on the Interstate it just couldn't keep up. Not really geared for it and lacks sufficient power anyway. For reference, if you've ever driven up Boulder Canyon, most of it is a gentle grade at 45-ish mph and the Troopy did fine, but the Narrows (the steep bit--12% grade-- just after Boulder Falls) was second gear.

watch the auctions until something you're interested shows up. They do all the work for you until it arrives at a U.S. port. They will require earnest money, but if you don't buy anything, you'll get it back.

I can't tell you what to buy, but if you want the thrill you think you'll get from a 70-series, is a 100 or 200 going to give it to you?
