Wow, 160k miles! It seems like a generation away for me. I bought my 98' Corolla at 50,800 miles back in May 05'. It's up to about 62,400 now. In 20 months, I've put on 11,600 miles.
Calculations:
Average miles per year: 6,960
Average miles per week: 133.5
Average miles per day: 19
Tank Capacity: 11.3 Gallons
Estimated average MPG: 29.5
Best Average Calculated: 32.2
Driving Conditions: 50% stopless driving, 50% stop-and-go
Bad Driving habit(s): Fast acceleration
Miles on full Tank: 333.35
Time per fill-up: once every 17 days (estimate)
At my current stats, it would take me little over 14 years to hit 160k, around the end of 2020. To hit 300k would require me about 34 years and 1.5 months, or around February of 2041. I'll be a 54 year old man by then (I'm 20 now). I hope I'll be able to hover convert my car by then and add Mr. fusion to the engine.
As for whether 160k is a good milestone, I don't know. I always thought that 100k was "the big moment", when a car passes its prime, but what do I know! It seems like everyone is driving these Corollas to their last breathe. I know of a 1988 Honda Civic in my old neighborhood that has 360k miles on it! The guy had to get a new engine for it at 280k. I suppose there is no real limit to any car's lifespan since parts can always be replaced, but rather there is a point at which the driver says it's no longer worth it to spend any more money to maintain their car. The point at which you need an engine swap is usually the killer for even the most reliable cars.
