Trading 6 Out of 7 Basses for Dream Car?

As I posted back in May of this year, I finally "retired" from steady gigging (22+ years of that with the same band), after roughly 31 years total of gigging. I've had a lot happen to me personally to force me to make the decision to quit gigging. For starters, I recently got a promotion at work that I've been after for years that requires more hours/responsibilities, and I've had major back surgery. Since recovering, I've taken up a hobby that requires a lot of money. The hobby? Taking my car (BMW E60 M5) to the track, when weather permits.
And, as I did in the music world, I've made a few friends. And, one of those friends also happens to be a bassist/collector. And, he also happens to own one of my all-time favorite dream cars that I've wanted since they hit the showroom floor in 1987. Bottom line: He wants 5 out of the 7 basses that I own (see my profile), in exchange for the car. At this time, value-wise, the car will increase like crazy in the years to come. And, I would also presently be coming out ahead in the trade, when it comes to the basses he wants, versus the current value of the car. He seems hell-bent on doing this trade. But, of course I'm kinda having hesitations on pulling the trigger. After all, I've owned these basses for 20 years, give or take. So, they're somewhat part of me. Since I've completed my collection of basses that I consider perfect for me, I haven't made another purchase. I'd also like to add that I've had probably a 1/2 hour playing time on my basses since October. Playing just doesn't interest me that much as of late.
The car is a 1988 BMW M3, in pristine condition with some very expensive mods that can be reversed to return it back to 100% original. And, like the majority of my basses, this car is highly desirable. I know that some of you on here just don't appreciate a machine like this with superior design, and engineering. I'm leaning pretty damn far towards doing this. But, I'd like to know what everybody's opinion is on this just for the hell of it, as it's obviously a pretty big financial decision. After all, I'm gonna do what I'm gonna do. Well? Speak up!

 

I'm with ya on that. I was into the muscle cars big time in high school. As a matter of fact, I owned a '66 GTO convertible back then. Love that tire smoke. I ended up selling it over a girlfriend. She's not around anymore, either.

QUESTION TO ALL: Why doesn't my threads show up every time on the homepage after I post it? It's been doin' that since the website revamp.

 

Here's my current basses. I think I'd be keeping either the Carvin 5'er, or my "wife" bass, a mid-80's Jazz Bass Special that's been gigged to death. That thing has been to war with me, and it shows big time. It REALLY has a place in my heart, for sure. I'd put pics up, but they're not on my new computer. I'll get 'em up first chance I get.

Pre-Gibson Tobias Classic 5
1961 J-Bass (Oh, she's been played hard, alright. But original)
1971 J-Bass (Modded w/Badass Bridge, I have original bridge)
1975 J-Bass (Modded w/Badass Bridge)
Mid-80's Jazz Bass Special (mint)
Mid-80's Jazz Bass Special (Plays like a wet dream, gigged to death, and it shows)
Carvin LB75 Koa (One of my very best players)

 

This car is valued at 30k-32k. Hell, maybe even more. It had a frame-off restoration 2 years ago So, I'd be doin' okay in the deal.

 

I've seen the value on these particular cars raise a pretty good amount over the past 2 years, or so. Recently, one sold for $62,000.00. It was in mint condition with only 23,000 miles on the clock. I wanna snatch a nice one before prices shoot thru the roof. And, it seems vintage J-Basses have dropped a hair, and vintage P-Basses seem to be goin' up in price. Huh, I'm glad I'm not a P-Bass kinda guy.
