I have been using Impex, Partsouq, Amayama, and Megazip for over 5 years. Here is a quick summary. Note I ALWAYS use DHL if available for all 4
PartSouq - Good pricing
Time: Usually the quickest in my opinion, from order to shipping to getting to your door. Rarely to never get emails about parts being unavailable.
Shipping Costs: Really depends on part weight, shipping from location and if using their new "express" service. Shipping cost is accurate at time of order
Tariff: Since the Tariff, I have not been hit with any cost on my end but I have heard stories of others being hit with cost from UPS/FedEx when the parts arrive stateside
Comments: For big purchases of OEM, 555 or other quality aftermarket I tend to use PartSouq as its the quickest and most convenient with Diagrams
Amayama - Good pricing
Time: 2nd quickest at fulfilling. I will occasionally get an email, that X part is not available.
Shipping Costs: Again depends on part weight, cost is usually accurate
Tariff: Since the Tariff, I have not been hit with any cost on my end but I have heard stories of others being hit with cost from UPS/FedEx when the parts arrive stateside
Comments: I usually use Amayama for smaller parts that I cannot get a hold of anywhere else but I have ordered in big and small batches.
Megazip - OK pricing
Time: Fulfilment speed is the same as Amayama
Shipping Costs: Really depends on part weight and shipping from location
Tariff: Since the Tariff, I have not been hit with any cost on my end but I have heard stories of others being hit with cost from UPS/FedEx when the parts arrive stateside
Comments: I only order 1 or few parts during their 20% off sale
Impex Parts - Great pricing!!!
Time: Fulfilment speed is the slowest of all 4. You need to place the order for the parts, wait for Impex to check if its available, wait for Impex to order it, then wait to arrive at the warehouse, pay to package the order AND THEN it goes out
Shipping Costs: You can estimate cost but will not know the final price until the order arrives. Even once the order arrives and is packaged up you might have to pay a bit more to account for the weight and size.
Tariff: Since the Tariff, I have not been hit with any cost on my end but I have heard stories of others being hit with cost from UPS/FedEx when the parts arrive stateside Update: I have been hit with a Levy. See my next comment below this post
Comments: I love Impex for their good pricing, quality of handling the shipment, and low shipping costs. Sure you do not know the cost to ship upfront but in my experience it has always been reasonable and affordable. I have ordered everything from brake boosters, to AHC globes, to trim pieces and heavier suspension bits.
If a part you paid for is unavailable the money gets released into your Impex account and you can email them to get your refund back to your bank account.
I think everyone just needs to be patient and understand that Impex does not keep parts on hand like the other 3. There is a few weeks wait from order as the parts have to arrive, then packaged and then shipped. Each step requires customer input to approve costs.
There are SOME parts that are actually cheaper stateside when you factor in shipping and handling.
