More Car (Auto) Advice

[RobertInOntario]

I know this is a train forum but I've always received good car advice here too! So here's my question:

My wife & I have two "aging" cars with fairly high mileage. We have a 2003 Subaru Legacy (our family car) and a 1998 Honda Civic (which I often use). Here are their descriptions:

• 2003 Subaru Legacy -- has about 185,000 km (about 116,000 miles) on it
-- body in good shape, very little rust but lots of scratches
-- has had several costly repairs during 2009-2011 -- (new transmission, has had the clutch replaced twice) and there may be other things to go on it too such as a possible steering problem that my local garage has been monitoring for us.
-- otherwise running fine now

• 1998 Honda Civic
-- has 215,000 km (about 134,000 miles) on it
-- has had very few major repairs, mostly regular maintenance
-- body is beginning to rust, especially bad around rear fenders. Like the Subaru, it has many scratches (thanks to living in a big city!) The hood & 1-2 other areas also has some rust and/or paint problems
-- otherwise it runs very well & smoothly!

One of these will need replacing soon -- but, based on the above, which one should we replace? Should we keep the Subaru going and replace the Honda since it's older and in rougher condition, or just wait it out another 2-3 years? The advantage of replacing one of them (probably the Honda) right now is that this makes us in control of our circumstances, rather than having us suddenly scramble to buy a newer car if it suddenly dies.

Thanks in advance for any advice!
