I’m going to take a contrary position, for what it’s worth. A high mileage Japanese car IS likely to be more reliable than a similar American car. BUT, that is no secret anymore, is it? In fact, that has become conventional wisdom these days, so market prices reflect that. There once was a time when Americans wanted to be loyal and “Buy American” so the market prices of each were affected and Japanese cars were a steal. Those days are long gone and prices show it, ESPECIALLY used prices. Around here (Chicagoland), a 100,000 mile 2002 Civic will easily go for TWICE the price of a 100,000 mile 2002 Saturn SL1. If your husband is remotely handy (can change brakes, EGR valves, etc), the Saturn is a steal versus the Civic and will ALSO go 200k miles (presuming you check the oil and keep it topped up).
This past summer I cashed out my newer car and bought a 2002 Saturn SL1 for $2,700 with 98,000 miles on it. A comparable Civic would have easily been $5,500 or more. I’ve replaced all the fluids, belts and filters for a couple hundred bucks and am now enjoying 38mpg in my commute instead of the 24 I used to get in my former company car Cadillac CTS (vestige of the ‘old economy!’) Unlike an early 90’s Civic, it has modern 2 stage front airbags and side head curtain airbags (they were an option - check!) for vastly improved safety over any comparably priced Civic or Corolla. Not a small concern for a teenage boy driver! Also a plus is that the thing has a measly 100hp, so even a teenage boy can’t cause too much trouble with it.
If you can’t do simple maintenance and repair work yourself, you may still be better with the Civic. But you’ll pay a LOT more up front and/or get an older model with less safety features for your money. If you live in a climate with winter and road salt, this all becomes even MORE true. There ARE no native early 90’s Civics left around here (Chicagoland). Their engines may still be in top shape, but the whole car is in the junkyard due to rust! At the very least, the rear bumpers have all fallen off due to rust at the connection points.
Food for thought.
Domestic models I think are a bargain / underrated:
Saturn SL series (often they use some oil, but the cause is harmless if you keep it topped up, fatal if you don’t)
Ford Escort, Saturn Ion, Saturn L Series (2002 or newer only), Ford Focus (2002 or newer only), Buick Regal (ask mechanic to check for signs of past intake manifold gasket leak though), Chevy Impala (3.8 V6 only, 3.4 is more trouble), Oldsmobile Alero (4 cylinder), Ford Ranger pickup.
