Tahoe Travler

Found out I have Five Star today. Not sure if I received 5 star from Amex Plat in gold profile or rental history last year. But after numerous unrequested minivan assignments in 900 numbered spots (a significant hike from gold canopy), I took a break from Hertz and car rental. I've used Uber Cab on all LAX trips so far this year. But, today I had to rent a car. My gold profile full size with GPS was automatically upgraded to a Mercedes C250 per "carfirmation" email when I landed; no upgrade charge. Nothing like this has ever happened before. Then, I was offered a further upgrade when gawking the really cool cars by Gold area. Four forms of ID later, I had cherry red a 2014 Porsche Cayman, mileage charges waived, and only a $100 up charge/day. That brought the total rental per day to $152+tax/fees/unlimited mileage. I NEVER would have gotten this in previous gold status years. Contract says 5 star, so I have to wonder if this is actually a significant bump up or dumb sunday luck at LAX.
