It's doable, but it takes some practice.
The biggest thing you can do to save a cars interior is to tint the windows. Even if it's not TINTED, it's UV protection. YEs, untinted "tint" for the windshield is a good thing too!
When I moved to Colorado, that was the first thing I did. Every car since ended up getting tinted right away.
Here's the thing - I am a klutz with those things, but I still don't want to spend a fortune. I found a place (in Longmont, btw, MMM) that does it cash, no receipt, for $150 to do my car. He even used proper 3M film for it. Yes, it's a lot, but it will last and not bubble up, it will also not turn purple in a few years and I had the car back that same afternoon!
This car was chosen for it's low cost of purchase, dirt cheap spare parts, ease of repairs and not NEEDING repairs! ~23mpg, lots of cargo room, and rear-wheel drive, which I wanted for the snow in Colorado (I came from a no-snow state). $2300 with 150K miles. Prior to this, I only owned a motorcycle.
This was the '93 VOlvo 945 before tint:
This is the car with LEGAL tint - I like the looks and it's UV protected inside now;
