Just about two years ago, been in and out of wheel chair, and walking devices for two years. I’m finally able to walk unassisted. I find it appalling that my ex employee that worked here for 8 years, and I’ve tuned cars for him off and on for 20 years now is on his little safe space YouTube channel talking s**t about me. Truth is he’s always like to kick me when I’m down, it’s not the first time so there’s no shock. It’s just some low s**t, I figured he might of grew out of being a hater. You wanna talk s**t and air it on josh LSX/LTXspecialist(415)710-2428 I know where all the bodies are buried so to speak, you are far from perfect sir. You shouldn’t throw stones in glass houses. I guess your head is too big now from social media hyping you up like you’re as big and better than all the shops in the game like Late Model Performance and Race Proven Motorsports 😂 jealously is an ugly look bud, and your YouTube videos are ridiculous, your shop is a disaster, I guess people can’t tell you’re full of s**t. I don’t know how anyone in thier right mind would pull up with half your shop Barfed out in the parking lot would think yea imma get work done here. Just saying. You wanna be famous, I’ll make you famous. Shots fired.
