OP - Do what you want with your $250K! It's for sure your choice to make.
That being said, I too am in the camp of recommending to 'Drop years to remain within budget range, and purchase the highest quality coach that you can find, that meets your personal needs.'
-Quality lasts, and is good foundation to say buy a$225K unit and save $25K to modify to your specific personal likes.
-Depreciation cliff becomes much less steep, not a more gradual decline, but just dropping 3-5 years.
-Safety. A higher quality coach usually also has a better safety cage around the occupants.
-10 years from now, a higher quality 5 year old coach, will still be more satisfying and solid to drive, the a new/newer coach of lesser quality.
-You could also get a 10 year extended warranty on an older coach, if that is important for peace of mind.
I'll stop, as again, it is your money to spend how you desire. And some people really do 'want new' - and until it is a penalty on your income taxes for not having bought a new coach, you can do as you please
If you do some more research, and decide to go the bit older router for a higher quality coach to start with, you'll find lots of good threads on higher end coaches to consider. And always feel free to ask, as you can see - this gang is always willing to provide opinions, and help you spend your money!!
Best to you, and congrats on getting to a point in life where you can make such a decision!!!!
