Just wanted to share some love to Harry's euro and their team! Bought parts for my r32 and gti, they never disappoint. Love being part of the euro community in an ever so dominant jdm culture in New Zealand. Looking forward to bringing an rs3 in for tuning :)

I've been a loyal customer of Harry's Euro since 2017, and I can confidently say Scott and his team are the best in the game. Not only do they consistently offer the best prices, but the service is always top-notch. Scott is honest, transparent, and always takes the time to explain what’s going on with my car. Whether it's routine maintenance, unexpected repairs, or upgrades, I always know my car is in the best hands. Highly recommend to anyone looking for a reliable, expert mechanic!

Used Harry's Euro for years owning a Mk6R and now a Mk5 R32. Amazing service and delivery! R32 kit arrived today with some extra goodies! Pleasure to deal with the team!

Hands down the best Euro shop in Auckland. They've looked after 2 builds of mine, and the parts, service and expertise has been top notch.

Harry's Euros delivered platinum service from start to finish. The quality of the products is excellent, and the install experience was smooth and professional. If you want a lower cost acceleration boost ask Scott about a Pedal Box! Huge difference and very simple to use.

Got some basic servicing and a Stage 2 transmission tune done today to match the ECU tune. The team was really helpful with information, communication via email, fit me in quickly, and offered fair, industry standard pricing for a specialised shop. Highly recommend, and I'll definitely be back!

Great service. Needed a replacement driver's side mirror glass for our old GTI. Harry's Euro had it in stock for a good price and shipped it next day. Very pleased with the transaction and will happily recommend and use them again.

Been Working with Harry's Euro for almost 3 years now and I can highly recommend any auto-work or performance upgrades to be done by these guys. I've had my previous car and my current done by the team cheers to Scott and the boys for the work 🍻
