I wouldn't waste your money on another PPI if I were you. I had a PPI done at European Performance in St. Pete's, based on recommendations from people here on Pelican. Here's what they found. Admittedly some of it is nitpicky, and there's a question as to whether the leakdown test was complete, but certainly there was enough to make me run far away. Certainly the car is not at all as described in the ad.
Compression/leakdown test showed 145-150 psi on 1-5, 4-5% leakage, 125 psi/70% leakage on #6
cabrio power top is inoperable - roof motors/transmission need to be replaced
Seats are vinyl, not leather
new convertible top and headliner needed
crack in centre of dash
needs a new fan housing (cracked)
something wrong with brakes, possible caliper needs rebuilding, needs hoses
front cooler hoses have slight weeping
oil leak at pulley shaft
lower valve cover seal leaking
needs new ignition wires (badly cracked)
paint blisters on front bumper
R door has a poor repaint 3-4/10 quality
ding in driver's door
needs new shifter bushings
needs new drive belts
roof light stuck on
headlights foggy
battery tie down missing
alarm is flaky, should be removed
gas cap paint faded
oil lines to/from t-stat bad
a lot of body rake - rear is set too high
RF wheel well pulled out a bit
tires are mismatched, cheap tires, decent life left
hood safety catch is broken
windshield rubber bad, could leak
driver's mirror doesn't move to the left
driver's mirror glass coming loose
needs high beam switch
Long discussion here if you want to read it:

TLDR: my opinion is seller is dishonest, car is very sub-par, worth low to mid 20s.
