JanTx - As has been mentioned, the BT Cruiser was considered an equal or better to the Trail-Lite with about a $5,000 higher new price. The Born Free is again another step better than both and with a corresponding higher new price. Born Free's are considered one of the better constructed units.
The mileage of the BT Cruiser of 65k miles and the Born Free of 80k miles makes them worth less. Both still have much useful life, but will start needing some TLC mechanically such as transmission, alternator, starter, brakes, power steering, radiator, hoses, belts, etc.
Be sure to look at the tires, not only the condition; but the age. There is a manufactured date code on them. Learn to look for them and be able to understand what they mean - for example {2305} means the 23rd week of 2005. The consensus of opinion is to seriously start considering replacement when over 6 years old. That can cost between $1,000 to $1,500.
