New car suggestions

My wife has a 2000 Honda Accord with 41,000 miles, runs good (4
cylinder), body in pristine condition. It's just getting old.

My dilemma is whether to buy a new car at this time, considering
there will be major changes in cars in the next few years. We are
in our 70's, and her next car will probably be her last one.

I'd like opinions on whether to run the Honda for another year or
two, or go ahead and get another car at this time. I'd like pro and
con ideas.

We are thinking of something a bit nicer for her next car, perhaps
something like a Toyota Avalon.

Thanks for your input.
