What your neighbors are saying
What we work on
From routine maintenance to major repair, we care for domestic and import cars, SUVs, and light trucks. Every service starts with a comprehensive digital inspection — photos, plain-English explanations, and an estimate before we touch a wrench.
Brake repair & replacement
Pads, rotors, calipers, brake lines. Hear a squeal or feel a soft pedal? We’ll diagnose it and tell you exactly what’s needed before any work starts.
Engine diagnostics
Check engine light on? Our technicians use professional-grade scan tools and decades of pattern recognition to find the root cause — not just the code.
Oil change & maintenance
Premium Valvoline oil and Napa Gold filters as our standard — because the small services protect the big ones down the road.
Wheel alignment
Newark roads — particularly after pothole season — are hard on your suspension and tires. A proper alignment saves you both, and we can usually have you back on the road same day.
We’re your trusted neighbor who happens to be great with cars
We’ve been part of the Northern Delaware community since 1986. Today our shop is owner-operated by Jon Seitzer — a Marine veteran and University of Delaware alum — backed by a team of technicians who average 30+ years in the bay. We’re a NAPA Auto Care partner, we use premium name-brand parts, and we treat every customer like a neighbor.
What sets us apart is how we talk to you. Every vehicle gets a comprehensive digital inspection — sent straight to your phone, with photos and plain-English explanations. You’ll know exactly what’s going on with your car before we touch a wrench, and your estimate will be upfront, transparent, and pressure-free.
Our Top Product
