...well, that certainly sounds like the email address of a shrewd buisnessman.
You gotta remember, to a lot of people these are 17-year-old economy cars, and they are, to an extent, perfectly correct. They pick a price and list the car. With non-collector/cult cars, lower mileage will increase the selling price, but not super-dramatically. To her, it might just be a '89 Civic with a couple of problems. I am as skeptical as the next guy when it comes to getting ripped off, but it's not like this is a Ferrari selling for $2100. Hell, if I was looking for a car, I'd probably hit Buy It Now before some jerk bids $101 and ruins it. If the car ends up as a regular auction, she will get what it's worth anyway.
Although, I just looked at her feedback...she's sold a $9000 240SX and a $10,000 Supra. This person might have a high-end daily driver, a fast project car, and what to her is basically a beater. Who knows.
Looking out for scams is smart, but you can miss out on a lot of good deals by thinking they are too good to be true. A low mileage CRX for 2 grand isn't too good to be true, it's a good deal. A $2,000 C6 Corvette is too good to be true
If you're skeptical, you place the winning bid, send NO MONEY, and tell the seller you'll be there in person within x number of days to see the car in person, pay the full amount, and take delivery. Sending huge deposits and crap like that is where the risk comes in, but it can easily be avoided.
Some people want to pre-approve bidders, BTW, because they've been burned in the past by non-serious bidders, zero-feedback bidders that never pay, 15 year old kids with no money, etc. Some sellers say "if your feedback is less than 10, email me before you bid or I'll delete it." This is the same type of thing.
