January 2105 I was faced with that decision. Replace my 2001 Civic with 235,000 miles or upgrade to a better bike. The bike won and I purchased a Trek Emonda SLR... love it.
So yesterday my Civic, now with 260,000 miles, started to overheat. Winds up its got a bad head gasket... so now it's time for the car.
Bummer, sure glad I made the right decision and had my priorities in order.
Unfortunate i'll now be in violation of Rule
#25 .
