I think with 150k I'd be off to the classic auctions - ether chasing a mint DB4 Vantage or either a Maserati A6G (though 150k would be a finance 'deposit' on one of these!) or a Bizarrini 5300GT (beautiful!) - or a beaten up 300SL Gullwing that I could restore in my retirement and in the meantime just oggle in the garage.
