You can probably further divide the 914 market into pre '73 and post '73. Later cars had lots of improvements. Relocated fuel pump, better shifter, improved interiors, etc Of course the earlier cars were lighter and better looking without the ugly rubber bumpers. Depends on which is more important, looks or driveability.
I have been watching that market here in Arizona where there are lots of rust free examples, probably not much different than Tx.
Good driver cars are selling here for right at $5k. Really special cars may jump up to $7k.
I had planned on going to see this car before they pulled the auction. I believe it had a day left and the bidding was around $4200.
