I used to own a 172,, So, remember all costs are proportional to size of the airplane,,
I put on about 1100 hours in my 172,, 90% of the time it was just me, about 5% it was with 2 on board,, the other 5% of the time,, there was more then 2, so you need to really understand your needs and all that.
Would I like to have my 172 back, yes, but would I want to pay for all those little extra costs,, nope, so I now have my 150 and most times, it's still just me flying,, I just get around a bit cheaper is all,,
