Long Story made Short...
I have had zero (0) speeding tickets since I bought a used Escort 8500 x50 S7 about five years ago... Except for one (1) I got last summer, with my RADAR detector in my glove box!
I have had to send it in for re-calibration three times since owning it... This was back when it was $60 to service the unit... The third time, they actually serviced it free and that was maybe 2011... Every since it's been HOT and virtually 100% reliable for 3 years.
I bought a new car, a NEW 2013 G37 (had 8 miles on the odo) because I despise the new Q50, with it's bull**** Steer-By-Wire system that feels like you are in a "driving simulator."
Suffice it to say the last car 2008 Mazda 3 S Touring 2.3 Liter 4-Cylinder had 153 horsepower (stupid Calif ULEV/PZEV B.S.) and a mere 149 lb/ft of torque with a 5-speed autobox and redline @ 6,500 RPM. The engine made 66 HP per Liter, which placed it at 19.5 pounds per pony!
New car is a 3.7 Liter V6 with 328 horsepower and 269 lb ft. of torque... The car weighs in at 3618 (vs. 2983 for the Mazda), so it weighs a mere 21% more! For that it has 2.14 times the horsepower and 1.8 times the torque! It's right at 11 pounds per pony! I also really like that it is Rear Wheel Drive and has a 7-Speed autobox, BUT there are days when I still urge for the 6MT.
Regardless, I can see the writing on the wall... this car is relatively FAST, feels sporty with awesome double-wishbone suspension and road-feel, yet it is quiet to the point you can care on a conversation whispering at 80 MPH on the freeway... Long story short, it is a speeding ticket waiting to happen!
Okay, so on the 13th, I ordered a brand, new Redline direct from Escort! It is clearly superior to the 8500 x50 and debatably better than the new Max for sensitivity & alerting though no fancy GPS and extreme filtering (i.e. the Max is probably superb for running in the City).
I receive my detector on the 17th! W00t!
Today, I test the new detector and SERVICE REQUIRED! WTF?? Try it again and SERVICE REQUIRED!!!
Brand, new in shrink wrapped box direct from the Radar Laser Experts and that... Dammit!
I just got done driving ALL weekend with no detector at all. My neighbor has been eyeing my 8500 x50 S7 and offered to buy it... said to make him a "fair" offer, so I sold it to him for $80 because I can forgo the eBay listing, fees, messages/questions, shipping costs, etc... AND that is EXACTLY what Escort would pay me for it as a Trade-In! I made it clear that there is A) No warranty B) that it is an older S7 sent in last in 2011 and C) that the Smart Cord is a bit jacked up... and that should any problems arise, I WILL refund it within my trade-in period (30 days) because it would be a simple matter to send it into Escort and still get $80 from them.
Regardless, he has text-ed me to tell me just how wonderful the 8500 x50 has been saving him, and I drove naked (no detector) all weekend.
Finally got my Redline and doh!
